military or fbi or other personnel can't do it? >> well, wolf, for one thing, when we go in -- when journalists go in, they don't go in as representatives of the united states government, right? we're media personnel. and there's a certain respect and sort of safety in that. anybody who goes in there representing the united states government is, you know, because it's not just the individual, they are representing our nation. so they are at greater risk. i will tell you though oftentimes in working with the host country's service, in this case the libyans, we can get direct access. and the fbi investigators i've spoken to have made perfectly clear it's much more effective to be able to be present even if you're doing that interview alongside the host government than to have to do it through passing questions. there's plenty of room for misunderstanding, for a lack of follow-up and information. so it makes for a much more effective investigation if the fbi can get permission to have direct access along with their libyan counterparts
